In September 2021 the US Preventive Services Task Force set its current position on chlamydia screening. Sexually active women 24 and under: screen annually, a Grade B. Sexually active men of any age: an I statement, meaning the evidence is insufficient to weigh benefits against harms. Coverage, quality metrics, and clinic reminders all follow the recommendation, and there is no recommendation for you. Nobody will offer you this test. You have to ask by name, and know which version to ask for.
No screening recommendation means nobody flags you
An I statement does not mean screening men is useless. It means the trials have not been done. The Task Force wrote that "the current evidence is insufficient to assess the balance of benefits and harms of screening for chlamydia and gonorrhea in men." Its research-needs section names Black populations as a group where the evidence is thinnest.
The result is a hole you can fall through. A woman of 22 gets a system prompt telling her clinician to order the test. A man in the same clinic gets blood pressure and cholesterol checked, is never asked about sex, and leaves carrying an infection a week of pills would have cleared.
Much of that cost lands on women. Chlamydia is curable, but treatment leaves no immunity, so a treated woman with an untreated partner is reinfected on the next exposure. That is why the CDC recommends retesting about three months after treatment: a positive retest usually means an untreated partner, not a failed antibiotic.
A urine test is not a full test
The standard test for a man is a nucleic acid amplification test, a NAAT, run on first-catch urine. It is accurate, and it checks one place: the urethra. Chlamydia also infects the rectum and the throat, and those infections never show up in urine, because the sample never touches the infected tissue. Finding them takes a swab of that site, ordered separately. Our guide to what a standard STI panel covers and skips quantifies how much a urine-only test misses.
The blind spot has been measured. Among 13,476 cisgender men seen at a Los Angeles sexual health clinic from 2018 to 2020, urine testing alone would have missed 86.1% of rectal and 89.7% of pharyngeal chlamydia cases. A 2016 review put the range of extragenital infections missed by urogenital-only screening at 14% to 85%, and found most of them cause no symptoms. Silent plus untested is how an infection circulates for years.
The CDC's 2021 STI Treatment Guidelines recommend screening by anatomic site based on the kinds of sex a person reports. That is where it breaks. The test gets ordered only if the clinician knows to order it, and the clinician knows only if somebody asks. Extragenital screening rates in US practice stay low, partly because sexual histories never get taken.
This applies to any man who has receptive anal or oral sex, whatever he calls himself and whoever he sleeps with. The ask is short: a rectal swab, a throat swab, or both, in addition to urine. You owe nobody an explanation for it.
What chlamydia does in a man when nobody catches it
The common presentation is urethritis: discharge from the penis, burning on urination, itching inside the tip. Plenty of men have nothing, or symptoms mild enough to blame on soap or friction. Mild is not absent, and absent is not uninfected.
The complication that lands men in urgent care is epididymitis, inflammation of the coiled tube behind the testicle: pain, tenderness, and swelling on one side building over a day or two, sometimes with fever. In younger men it commonly comes from chlamydia or gonorrhea traveling up the urethra. It responds to antibiotics and needs same-day evaluation for one reason. The condition it is most often confused with is testicular torsion, where the testicle twists off its own blood supply. Torsion is a surgical emergency and the window to save the testicle is hours.
Chlamydia can also trigger reactive arthritis, joint inflammation that follows an infection elsewhere in the body rather than bacteria inside the joint. It is uncommon and treatable. Joint pain in the weeks after a genital infection is worth raising.
You will also read that chlamydia causes male infertility. Be careful with how firmly that gets stated. In women the link to tubal damage and infertility is well established. In men it is not. A 2023 systematic review of eleven sexually transmitted pathogens found the chlamydia evidence limited and inconsistent, with no clear causal association established. Get treated for the disease it causes and the transmission it drives.
The numbers, and what they actually measure
NHANES tests a random national sample instead of counting who walked into a clinic, which makes it the cleanest picture available. In NHANES data covering 2011 to 2016, about 5% of Black adults aged 18 to 39 tested positive for chlamydia, the highest of any group measured and little changed from 2005 to 2010. Prevalence among men overall rose from 1.45% to 1.94%.
The figures usually quoted are a different animal. CDC case rates count infections that were diagnosed and reported, and both steps are unevenly distributed. Reporting from public clinics is more complete than from private practices, and public clinics see a disproportionate share of poor and uninsured patients, who are disproportionately Black. A 1997 Institute of Medicine review said it plainly: that reporting bias skews the demographics of reported rates, and measured differences between minority and white populations may be increased by it. Any chlamydia rate broken out by race partly measures who gets tested.
What remains is not a behavior story. Black Americans do not report more sexual partners on average. The explanation with evidence behind it is network structure: inside a partially segregated sexual network, background prevalence drives the risk carried by any single sexual act, independent of partner count. Laumann and Youm's 1999 analysis in Sexually Transmitted Diseases made that case with national survey data. Add slower access to testing and treatment and the mechanism is complete. The National Academies' 2021 review closed the biological question: no data indicate a biological reason.
Treatment is one week of doxycycline
The CDC's 2021 guidelines make doxycycline 100 mg by mouth twice a day for seven days the recommended regimen for uncomplicated chlamydia in adults. Azithromycin 1 gram as a single dose moved to alternative status. Doxycycline is preferred partly because it performs better against rectal infection. Finish all seven days, and avoid sex for seven days after starting and until your partners are treated.
Your partners have to be treated or you will hand it back and forth. Expedited partner therapy is a clinician giving you medication or a prescription to pass to a partner who has not been examined. Randomized trials, including Golden and colleagues' 2005 trial in the New England Journal of Medicine, found it raises the share of partners treated and lowers reinfection. Legal status varies by state, so ask whether it is available where you live. Retest at about three months.
Where to get tested without a primary care doctor
A guide that assumes you have an annual physical is useless to most men reading this. In a national analysis of National Health Interview Survey data from 2006 to 2014, Black men and Black women fared the worst of any group on changes in health care access, and Black adults were among the least likely to report a usual primary care provider. The routes that need no doctor:
- Local health department STI clinics. Many test and treat free or on a sliding scale, and they already run site-specific swabs.
- Title X family planning clinics. Federally funded, confidential, sliding scale by income, and they serve men.
- Federally qualified health centers. Sliding scale regardless of insurance. HRSA runs a national finder.
- At-home collection kits. In November 2023 the FDA authorized the first over-the-counter at-home collection test for chlamydia and gonorrhea. The male sample is urine, so it skips rectal and throat sites.
- The CDC's GetTested tool lists testing locations by ZIP code.
If you want a clinician you will go back to, find a Black primary care doctor or urologist in our directory. Bring two things: ask for a chlamydia and gonorrhea NAAT by name, and say which kinds of sex you have so the right sites get swabbed. If HIV prevention belongs in the same conversation, our guide to PrEP for Black Americans covers it, alongside low testosterone in Black men.
Frequently asked questions
Do men get screened for chlamydia at a regular checkup? ▼
No. The USPSTF issued an I statement for chlamydia screening in men in 2021: the evidence is insufficient to recommend for or against it. Clinic reminders follow the recommendation, so nothing flags you. Ask for a chlamydia and gonorrhea NAAT by name.
Does a urine test check for rectal and throat chlamydia? ▼
No. A urine NAAT detects urethral infection only. Rectal and pharyngeal chlamydia need a swab of that site, ordered separately. In one study of cisgender men, urine testing alone would have missed 86% of rectal and 90% of throat cases.
What does chlamydia feel like in men? ▼
Often nothing. When symptoms appear they are usually discharge from the penis, burning on urination, or itching inside the tip. Rectal and throat infections are usually silent. Pain and swelling in one testicle needs same-day care.
How is chlamydia treated in men? ▼
Doxycycline 100 mg twice a day for seven days is the CDC's recommended regimen; azithromycin 1 gram once is an alternative. Finish the course, avoid sex for seven days after starting and until partners are treated, then retest at about three months.
Where can I get tested with no insurance and no doctor? ▼
Local health department STI clinics, Title X family planning clinics, and federally qualified community health centers test free or on a sliding scale with no existing primary care relationship. FDA-authorized at-home kits are another route, though the male sample is urine only.
